Manufacturer Recall No 6023G NHTSA Recall No. 23V-487 Rear View Camera has NOT been repaired. How long more do I have to wait for the repairs to start? It has been over 6 months since the recall notice went out but I have had the issue for years now. Please step in and make Mazda make good on their products. I have called several dealerships but they all tell me that only Mazda headquarters knows when the repairs kits will become available. So, when is that? Do we wait until more accidents happen so the lawsuits increase over this matter? Last time I checked they are still putting out thousands of cars on the road...does that mean they are too busy to take care of these issues since, after all, they have already pocketed our monies and now we are pushed to the side as if we don't matter? I await great news.

Infotainment system / center console doesn't work properly. Buttons would be pushed at random, changing stations and flipping thru menus. It deteriorated to the point where it would constantly reset itself, flashing a very bright (and not dimmable) Mazda logo over and over. Mazda insisted on charging for repairs so I have instead simply removed the center console instead. otherwise the bright flashing light at night was distracting to the point of dangerous.

The backup camera is flickering and with distorted image. I called customer service but didn't provide information or solution of how to solve the issue even though they were aware of it.

Recently noticed the odor of unburned gasoline, both inside and outside the vehicle. When driving, the ventilation system would flush this away in a few moments, but this phenomenon is new within the past few weeks. Our mechanic (not the dealer) traced the issue to the fuel tank, where the port for the fuel pump and sensors is located on top. This area is accessible by removing the rear seat cushion and a cover plate. He showed me how the fuel pump and sensor module has rusted to the thread of the port, preventing removal of the assembly, and that the port flange itself has rusted and has pin-holes, allowing vapor to escape. He was able to put slight positive air pressure to the tank as a test, and was able to cause liquid fuel to escape from the holes. The tank was about 3/4 full at the time. This seems like a serious safety issue. The port and matching threaded parts (fuel pump / sensor module) that inserts there should be corrosion-proof. I can provide a photo of the affected area if needed; I would get the image file from my mechanic.

ac/heat knob will not go into max air due to a cable slipping off the mechanism behind the dash when it does this the heat will not work and it is hard to defrost your windows if they get fogged up while driving making it difficult to see

When cleaning and adjusting the seat to move it to forward-facing, we discovered that two of the child harness straps (the crotch strap and one of the shoulder straps) had significant grooves cut into them, presumably by the plastic edges of the base. Given that this damage was not visible before moving the cover and adjusting the seat, and given that Graco advertises this seat as rear-facing from 4 to 50 pounds and forward-facing up to 65 pounds, a consumer wouldn't see or have any reason to expect this level of damage after about 3.5 years of use. I have to assume that this sort of severe wear compromises the strength of the straps and thus the safety of the seat if there were an accident (thank goodness we didn't have one). I have the seat still, and I contacted the manufacturer with pictures of the damage, and they did not seem to think it was out of the ordinary or alarming at all, just told me that they could send me a rebate for a discount on a new seat if I wanted since this one was out of warranty. I cannot believe that this is an acceptable and safe amount of normal wear. I can attest that we followed manufacturer instructions for care and install and did not use any cleaning products on the seat, submerge the seat, leave it outside, or do anything else that I can think of that would have constituted inappropriate care of the seat.

shock towers are disintegrating so the shocks would not be connected to anything.

Nothing has happened yet but Ive done a bunch of research and a lot of the 3rd generation Mazda 3's all have the same airbag code 16 flashing on their dash and it's not on any recall list

The rear backup camera on my vehicle goes on and off or dims considerably when I back up, not allowing me to see cars and people potentially behind me. This is associated, I believe, with an issue with the screen and infotainment system of the car, which I had checked out on 9/24/21 at a Mazda dealership. The screen goes on and off constantly, not allowing me to use the radio, bluetooth, etc. They said it is a chip issue that they have seen in many other Mazda 3's from 2016. Not being able to listen to the radio is one thing, but having the backup camera not work or work improperly is a safety issue.

Apparently all of sudden the front occupants seat belt had lock and malfunctioning to the point you are unable to pull the belt strap to securely wrapped around the passenger, took it to have it evaluated at the request of the auto maker, supposedly this what I understood from two separate auto repair shops ( Mazda) dealership and a reliable auto repair (Apex) shop stating that a spring loaded system mechanism part was actually missing and that the standard mechanical labor (code) cost for the repair were not (unknown) listed while the other suggested the whole seat belt needed to be replaced I strongly feel this should be a safety related issue for both the driver and passenger seat belts should be recalled and carefully looked into for driver/passenger safety reasons.

There is a main board failure that controls the information screen and back up camera The part number is TC3M-66-9C0B . The screen will keep rebooting not allowing the back up camera to work. According to Mazda dealer personal Mazda will not cover this. This is know to be a regular problem with many of these cars

Parking brake does not fully disengage. This causes the rear brakes to wear prematurely and also has the potential to generate excessive heat.

In mid-2021, the Mazda Connect infotainment system suddenly stopped working. Upon starting the car, the software boots over and over again. The Bluetooth is inoperable; radio plays but I cannot change stations; steering wheel functionality of these features is absent; backup camera is intermittent and dimmer. The latter is a safety issue. The Mazda dealer diagnosed a malfunction of the connectivity master unit (CMU) and said they have had a rash of the same problem with 2016's recently.

Timing cover leak, all maintenance was completed before the service bulletin. This is a TSB but should be a recall for how common this issue is as they stated it could be caused from the assembly line during a pressurized test. “ This may be caused by oil escaping from a fine clearance created at the sealant applied to joint (A)between the cylinder block (B) and head (C) when the engine was pressurized during leak testing on the engine assembly line.” TSB Bulletin No.: 01-018/18. Timing cover issues are not something that should be happening under 100k miles.

Front end passages side shaking with 60 mhg. And some time smelling gasoline when first started up my car.

The infotainment system fails to work - it is where I can access information re: maintenance schedule, or any info that is associated with a lit engine light. In addition the charging system for my mobile phone has ceased working. This includes both the usb ports and the lighter port which can be adapted with a charger that works in that receptable. These are all safety issues as far as I am concerned. Not having information related to the vehicle engine light is a big issue, but so is the fact that I can't charge my phone on long distance drives. If I needed assistance, I would be unable to contact anyone without a working cell phone. Because the display also controls the ability to pair a phone with blue tooth, there is concern for other drivers of the Mazda 3 (mine is a 2016) will be using the phone regardless of the bluetooth malfunction. I have seen a safety recall on other Mazda's with relation to the infotainment screen, but I do not see one here. I wonder why? To repair this crucial component would cost many hundreds of dollars -- something I am not in a position to do. Mazda claims this infotainment center is not under warranty, but with so much important information and safety features embedded into it, I think it should be corrected by recall. Thank you for investigating this issue. Regina

The windshield wipers work but the washer does not squirt the windshield washing fluid out and it the reservoir is full of fluid but there are certain days in which I need that to work because my visibility is greatly reduced which has made the risk of accident that much greater. it says there is a recall pertaining to this problem and the fix was a relay However nothing comes up for my specific car when I enter the Vin but I would like this problem fixed and I’m not sure how to go about it
